Framework and requirements for cloud computing                              1


            14      General requirements for end-to-end cloud resource management

            The  general  requirements  for  end-to-end  cloud  resource  management  derived  from  the  use  cases  in
            clause I.9 are as follows:
            –       Manageability for a single cloud service: It is required that the CSP be able to collect management,
                    telemetry and diagnostics and/or status information from the cloud computing systems used for
                    providing cloud services and report the information to the CSC;
            –       Manageability for multiple cloud services: It is recommended that multiple CSPs work together to
                    offer comprehensive status awareness and management information to expand across multiple
                    cloud data centres as composite cloud services are built from multiple services implemented by
                    multiple cloud service providers, requiring the need for multi-cloud, end-to-end management data.
                    NOTE  –  For  more  information  on  end-to-end  cloud  computing  management,  refer  to  [ITU-T Y.3520]  and
                    [ITU-T Y.3521].


            15      General requirements for cloud infrastructure
            The general requirements for cloud infrastructure derived from the use cases in clause I.10 are as follows:
            –       Resource  abstraction  and  control:  It  is  required  for  cloud  infrastructure  to  provide  resource
                    abstraction and control capability to cloud services;
            –       Resource provisioning: It is required for cloud infrastructure to provide collaboratively processing,
                    storage and network resources to cloud services and supporting functions.
                    NOTE – Functional requirements for cloud computing infrastructure are provided in [ITU-T Y.3510].


            16      General requirements for trusted cloud services
            The  general  requirements  for  trusted  cloud  services  are  derived  from  the  use  case  in  clause  I.11.  The
            following requirements are important for CSCs in order to be able to select a trusted cloud service. These
            requirements do not specify the levels and abilities of the cloud services, but require that the cloud services
            which are treated as trusted cloud services should satisfy the following:
            –       Governance for trusted cloud service: It is recommended for trusted cloud services to comply with
                    appropriate or local standards and best practices of corporate governance and include appropriate
                    mechanisms by which policies affecting the provision and use of cloud services are directed and
                    controlled;
                    NOTE 1 – Part of this requirement refers to [ITU-T Y.3502].
            –       Management for trusted cloud service: It is recommended for trusted cloud services to include
                    appropriate  mechanisms  for  administration,  reporting,  location  of  stored  data,  privacy,  de-
                    identification of data, etc.
            –       Resiliency  for  trusted  cloud  service:  It  is  recommended  for  trusted  cloud  services  to  include
                    appropriate mechanisms by which an acceptable level of service can be maintained in the face of
                    faults (unintentional, intentional or naturally caused) affecting normal operation;

                    NOTE 2 – Part of this requirement refers to [ITU-T Y.3502].
            –       Security  for  trusted  cloud  service:  It  is  recommended  for  trusted  cloud  services  to  include
                    appropriate mechanisms for cryptography, attack resistance, intrusion detection, security incident
                    handling and reporting, etc.
                    NOTE 3 – Part of this requirement refers to [ITU-T X.1601].
            –       Availability  for  trusted  cloud  service:  It  is  recommended  for  trusted  cloud  services  to  include
                    appropriate mechanisms for ensuring the appropriate level of access to the service and usability by
                    the CSC;
